We can use a similar form to ask someone if they know other places, for example, "Uyazi iTheweni?", "Uyazi iSoweto?" and even "Uyazi iLondon?". "Na" may be used to indicate a question in spoken language and in writing but when the language is spoken, generally questions are indicated with tone. This form cannot be used to ask if someone knows a person. This is because the of "uyazi" part of the verb. The y refers to the place iGoli basically u+i+azi becomes uyazi. Zulu does not allow vowels to be placed immediately alongside each other. The concept of object being attached to verbs is explained fully in a later lesson. We now introduce how to ask if you know someone.
